Wall-to-wall land-cover mapping at European scale for implementation, review and
monitoring of EU policies (e.g. water framework directive, biodiversity strategy,
common agricultural, regional policies) and also for reporting obligations under
international treaties (e.g. the Kyoto Protocol), in line with national land-cover /
landuse

Environmental seasonal / annual change monitoring in development upon request
from the user DGs (DEV, AIDCO, RELEX - plus high-resolution information on
sites selected according to a statistically valid Area Frame Sampling scheme (AFS),
as well as for hot-spot analysis.
Selected sites among those identified by the Land Product Validation sub-group of
CEOS for the validation of LR and MR biogeophysical parameters.
Medium and high resolution crop mapping upon request from national and
international users (FAO, WFP, Ministries of agriculture) - plus very high-resolution
information on sites whereby field information cannot be collected
Reduction of emissions from deforestation in developing countries for UNFCCC:
300 – 500 HR – VHR scenes over tropical countries for large area coverage. In
addition medium and low resolution multi-seasonal acquisitions to fill holes due to
cloud coverage. Archived (40%) and newly (60%) acquired scenes,
200 – 300 HR SAR images
